Serial No. 753,296.

ticularly adapted for the building of silos,

it may be useful for other purposes.

The invention includes a mam, central,

longitudinallyadjustable support which 7 may be disposed vertically for sustaining a plurality of radiallydisposed, horizontal arms upon which hangers or sheave-blocks may be mounted at any required radial distance from the vertical support, suitable stirrups being provided for the sheaveblocks to provide a mounting and support for a suitable scafiold or platform; means being provided for disposing and maintaining the radial arms at any required distance from the ground, and for supporting the platform at any required altitude to circumscribe the vertical support and wall of the silo; all of the parts to be so constructed that they may be conveniently assembled, and when desired may be readily disconnected to occupy a limited space for packing or transportation. 7

The invention consists of the novel construction, combination and arrangement of parts as described herein and claimed, and as illustrated in the drawing, it being understood that changes in form, size, proportion and minor details may be made within the scope of the claims, without departing from the spirit of the invention.

In the drawing, Figure 1 is a plan view of the apparatus, with the guy ropes and reel omitted, the cylindrical, upright wall of a silo being shown. showing means for pivotally connecting the sheave-blocks, the stirrup for the lower block being omitted. Fig. 3 is a transverse Fig. 2 is a View,

section through the supporting-frame and platform, on line 3 3 of Fig. 1, the tubular members being shown in longitudinal section. Fig. dis a detail relating to Fig. 3 to illustrate the use of the sleeves and their keepers. Fig. 5 is a transverse section through the tubes as on line 5 5 of Fig. 3, to show a plan view of the reel, and its mounting.

Referring now to the drawing for a more particular description, numerals 1, 2 and 3 indicate tubular members of different diameters to provide a vertical support 11 for sustaining, at a suitable altitude, the supporting-frame at, said members being telescopically mounted so that the vertical support may be extended longitudinally, as may be required. While I have shown and prefer to use three tubular members for this purpose, any desired number and of any desired length or diameter may be employed,

and any suitable means may be arranged for removably securing the tubes together in extended relation, the means herein shown being an arrangement of sleeves and keepers therefor.

Sleeves for the above purpose are indicated, respectively, at 5 and 6. By use of a keeper or set-screw 7, sleeve 5 may be secured upon tube 3, and when the parts are disposed in an upright position, the weight of tube 3 will be supported by sleeve 6 since said sleeve 6 is supported by tube 1, said tube 1 being supported upon the ground or upon socket-member 8.

By referring to Fig. 4, it will be seen that when tube 2 is extended outwardly of tube 1 its weight may be sustained by said tube 1, since its sleeve may be rigidly secured there on by use of keeper or set-screw 9, and when tube 2 is thus extended, collar 5 may bear upon the terminal of said tube for supporting the weight of tube 3.

hen used for building silos, the tubular members 1, 2 and 3 are secured together by use of the sleeves and keepers, and then they are disposed in a vertical position at the middle or center of the silo foundation 10 (Fig. 1). Since the height of silos is not uniform, the adjustable features mentioned are convenient, so that the height of the tubular, vertical support may correspond to the height of the silo to be built; and by means of the construct-ion, the parts mentioned may be readily separated for the purpose of being transported.

The supporting-frame 4 consists of the pair of spiders or collars 12 and 18, these being rigidly connected and maintained adjacent to each other, by links or spacingbars 14, the lower collar being provided with numerous, radially-disposed arms 15 sustained in substantially a horizontal position, by flexible members 16 secured upon said arms and to the upper collar 12.

At 17 are indicated hangers removably mounted upon arms 15 for the support of a platform 18, each hanger preferably consisting of a pair of sheave-blocks a and I) which may be detachably connected whenever desired by the pin 0 near their inner ends, blocks 5 being provided with stirrups.

03 Within which strips 6 of the platform may be secured by bolts f.

Since the hangers may be mounted upon any part, longitudinally of the arms, ad-

justments may be made thereof so that the platform, which ciroumscribes the vertical support 11 and the wall 18 of the silo (Fig.

' 1'), may have a greater or lesser length, and

this is an important feature, since the diameters of silos are not uniform. Strips e are provided, at longitudinal intervals, with apertures 9, within which bolts f may engage when making a longitudinal adjustment of the platform.

In operation, it is desirable that the platform may be raised or lowered, and this may be accomplished either by use of cables 19 of the sheave-blocks after pivot-pins 0 have been removed, or the supporting-frame 1 may be elevated or lowered by means of the reel 20.

Near the upper end of tube 3 are indicated pulleys 21 mounted upon suitable brackets 22; and at 23 are indicated cables, each having one of its ends mounted upon the collar 12. These cables, after passing over pulleys 21 and traversing all of the tubes and engaging roller it, may be wound upon the reel, said reel being mounted upon the lower part of the vertical support 11. Since the supporting-frame may be adjusted longitudinally of the vertical support, 'and since the hangers are longitudinally adjustable, the platform may be raised or lowered, as may be required.

At 24 are indicated guy ropes or cables, by means of which the tubes may be maintained in a vertical position. When building silos of less than ordinary height, the collars 12 and 13 may be disposed to circumscribe the lower tube, and therefore the apertures of collars l2 and 13 are of such extent or diameter, that tube 1 will fill said apertures when the collars are mounted thereon. lVhen arranging the parts for this purpose, the set-screws 7 and 9 may be temporarily removed.

At 25 are indicated filler-members or bushings, and when the parts are disposed as shown in Fig. 8, these'bushings are necessary to fill the space between tube 3 and the collars, so that arms 15 may be maintained in a horizontal plane, a swinging movement of said arms being prevented. 7

Blocks 5 of thehangers are provided with suitable staples 26 for holding a cable or life-line, to prevent personal injuries of workmen, when on theplatform, as by falluable time and building material, and this.

may now be avoided. 7

Having fully explained the several parts and their uses, a further description relating to operation is not necessary. t

What I claim and desire to secure byLetters Patent is,-

1. In combination, a first tubular member, a secondary tubularmember of less diameter than the first tubular member and slidably connected therewith; a' supporting-frame consisting of an uppermost collar, a lowermost collar, the apertures of each of said collars having a diameterequal to the diameter of the first tubular member, means to maintain the collars in spaced relation with reference to each other, a plurality of arms removably mounted in the lowermost collar, supporting-members extending between and connecting'the uppermost collar with the arms, said supporting-frame being adapted to be mounted with its collars cir-- cumscribing the second tubular member for disposing its arms radially with reference thereto; a plurality of bushing-members adapted to be removably mounted-in said collars for maintaining the arms in a horizontal plane; a plurality of longitudinally adjustable hangers slidably mounted upon said arms, and a longitudinally-adjustable platform supported by said hangers.
